You can use Ops Center Administrator to provision P-Vols and S-Vols and create high availability pairs. High availability is supported by global-active device technology.

To set up high availability, configure a virtual storage machine (VSM) in a secondary storage system, and optionally, in a primary storage system. A virtual storage machine can be configured using the actual information of the primary storage system, and the global-active device primary and secondary volumes are assigned the same virtual LDEV number in the virtual storage machine. This enables the server to see the pair volumes as a single volume on a single storage system, and both volumes receive the same data from the server. Alternatively, you can use virtual model and virtual serial numbers.
